Therefore, the quality of the roll forging process in the forging process is also continuously improved. In the past, the roll forging dies for the roll forging process of forgings were all processed by electric discharge machining. During the electric discharge machining positioning, a dial indicator was manually used to measure around the die for alignment. When processing the next roll forging die, the alignment needed to be repeated. This not only has low work efficiency during batch production, but also is prone to positioning deviation, seriously affecting the processing quality of the roll forging die and the quality of the forging product.
